[3] Known as the Eldora Dirt Derby, the event ran from 2013 to 2019; it was canceled in 2020 due to the COVID-19 pandemic and was then removed from the 2021 schedule.[4] Bristol Motor Speedway, a half-mile concrete short track, had its surface covered by clay when it hosted the World of Outlaws dirt late model and sprint car tours in 2000 and 2001.Although successful with over 85,000 in average attendance, the race was canceled after its second year due to logistical difficulties: 14,000 truckloads of materials were needed to convert the track to dirt regulations,[5] which resulted in damage to the streets outside, with 8,000 cubic feet of red clay being hauled in from a nearby farm for the surface.Rain had been in the forecast entering the weekend, prompting NASCAR to delay the heats on Saturday to deploy "packers"—vehicles like Ford Crown Victorias to pack the dirt together—and late models to test the surface's viability before starting the first heat; it only completed one lap before being halted due to mud accumulating on the trucks' windshields and grilles.[12] On February 13, 2023, it was announced that Weather Guard would become the title sponsor of the Truck Series Bristol dirt race in 2023, replacing Pinty's.
